Riyadh – Saturday-Sunday 20-21 May

Mr Trump will attend the Arab Islamic American Summit in Riyadh and speak about his “hopes of a peaceful vision of Islam”, in what aides say will be a speech the president hopes will resonate worldwide and express “a common vision of peace, progress and prosperity”.

Mr Trump caused controversy during his campaign by calling for Muslims to be temporarily banned from entering the US over security concerns. Legislation aimed at restricting travel from several Muslim-majority countries remains tied up in the US courts.

The summit agenda is expected to focus on combating Islamist militants and the growing regional influence of Iran.

Mr Trump has been a fierce critic of the Iran deal which eased sanctions in return for a curb on its nuclear activities.

One leader who will not be attending the summit will be Sudan’s President Omar al-Bashir. President Bashir is wanted by the International Criminal Court on war crimes charges and the US was reported to be unhappy about his planned attendance.

Unlike his predecessor, Barack Obama, Mr Trump is not expected to highlight human rights during his trip.

And aside from the formal diplomacy, US country music star Toby Keith will perform a free concert in Riyadh on Saturday alongside Saudi singer Rabeh Sager.

Saudi Arabia, which enforces a strict interpretation of Islam including a total ban on alcohol, is perhaps an unusual venue for Keith – whose hits include I Love This Bar, Whiskey Girl, and Drunk Americans.

Saturday’s concert is open only to men aged over 21 who are required to dress in traditional Saudi tunics.

Israel and the West Bank – Monday-Tuesday 22-23 May

On Monday, Mr Trump will fly to Tel Aviv and travel on to Jerusalem where he will meet President Reuven Rivlin.

He is due to visit the Church of the Holy Sepulchre as well as the Western Wall before holding talks with Israeli Prime Minister Benjamin Netanyahu.

Observers will be watching to see if Mr Trump refers to his announcement during the election campaign, that he would break with decades of US policy and move the US embassy from Tel Aviv to Jerusalem.

The status of Jerusalem is one of the most sensitive and complex issues within the Middle East conflict and no country in the world currently has its embassy there.

On Tuesday, Mr Trump will travel to Bethlehem in the West Bank for talks with Palestinian President Mahmoud Abbas. Peace talks with Israel will top the agenda and Mr Trump is expected to express his support for Palestinian “self-determination”.
